Cellular RespirationBasic information: Cellular Respiration is the process where glucose is being broken down with other food molecules in the presence of oxygen. There are two types of respiration aerobic and anaerobic. Aerobic respiration requires the use of oxygen that occurs in the mitochondria too release energy that is stored in food.

The Steps of Aerobic Respiration:

Glycolysis is the first step in cellular respiration, it occurs in the cytoplasm with the reactants of glucose, which produces pyruvate, ATP, and NADH. In the mitochondria pyruvates enters which converts into Acetyl Co-A.

Krebs Cycle is the second step in cellular respiration, and it occurs in the mitochondria matrix. The Acetyl Co-A that was previously the pyruvate,reacts and produces energy carriers such as ATP, NADH, and FADH2 and carbon dioxide, which is a waste product. Enzymes carry out the reactions.

Electron Transport Chain is the final step in cellular respiration, it occurs in the mitochondria criste. The reactants of this process are energy carriers (NADH, and FADH2) and they produce ATP, and water, which is also a waste product. The goal of the electron transport chain is to release more energy.


The Next Step is Fermentation which is Anaerobic Respiration....

There are two types of Fermentation are Alcoholic and Lactic Acid. Alcholic Fermentation occurs in the cytoplasm with yeast and a few other microorganisms. The reactants are glucose and the products are ATP, CO2, and Ethanol. Lactic Acid Fermentation occurs in the cytoplasm with specific different bacteria, and animal muscle cells. During rapid exercise when the body cannot supply enough oxygen to the tissues, lactic acid is produced in your muscles. The reactants are glucose and the products are ATP and lactic acid.Alcoholic and Lactic Acid fermentation
